Possible reasons why all gears in the automatic transmission are on:
1. Low or poor quality transmission fluid (ATF):
* ATF transmits power and lubricates the transmission.
*Low ATF levels can lead to overheating and burning of clutches.
*The wrong type of ATF may not provide proper lubrication.
2. Transmission fluid filter clogged:
* A clogged filter restricts ATF flow and can cause overheating and fire.
3. Worn clutches:
* Clutches transmit power between gears.
* Over time, clutches wear out and can lead to slipping, overheating and burning out.
4. Faulty solenoid:
* Solenoids control ATF flow and gear shifting.
*A faulty solenoid can result in improper shifting or worn clutches.
5. Faulty torque converter:
* The torque converter transfers and absorbs power between the engine and transmission.
* A faulty torque converter can cause the transmission to overheat.
6. Worn gears:
* Over time, gears can wear, resulting in increased clearances and reduced power transmission efficiency.
7. Transmission overheating:
*Overheating can cause damage to transmission components, including clutches and gears.
8. Electrical faults:
* Faults in wiring or electronic components may interfere with transmission operation and cause overheating.
Important steps to take:
* Stop the car as soon as possible.
* Shift the gear selector to ‘P’ (park).
* Turn off the engine.
* Call a tow truck.
* Take the car to a car service center for professional diagnostics and repairs.
